Andalusian chickens exhibit incomplete dominance and they can have black feathers (bb), white feathers (bb) or gray feathers (bb). what would the phenotypes of the offspring be if you mated a heterozygous male with a heterozygous female?
group of answer choices

75% black feathers, 25% white feathers

25% black feathers, 50% gray feathers, 25% white feathers

100% black feathers

50% black feathers, 50% gray feathers

The second answer is correct.

If we make a punnet square: (sry if its weird, i had to improvise, lol)

       B           b     -

__---

B  -  BB   -   Bb    -

__---

b  -  Bb    -  bb     -

We know that both the female and male are heterozygous, meaning the alleles are different, so one would be dominant, and one would be recessive( for both the female and male). So both female and male would be Bb, as on the punnet square. If we cross them, we get BB, Bb, Bb, and bb. So, 25% of that is BB, which is black feathers. We have 50% of gray feathers, Bb, and 25% white feathers, bb. Therefore, the second option is correct.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
